These sill bolts are really cadmium plated versions of the same thing. It does not really protect from the corrosion, the cadmium becomes the sacrificial metal and it corrodes instead. And they're sheet metal screws, so a few easy turns and they're replaced. The only hard part would be lining up the holes for the new ones. For the few dollars that the bag of six or eight screws cost, it's probably not worth your time to wait to have it serviced, IMO.
